The includes used to define a lot of things a library include should not. It was also a bit messy what was exposed in the library and what was not. get_pid_digits -> procps_pid_length and exported correctly MALLOC attribute move into relevant .c files NORETURN attribute moved to relevant .c, not used in library PURE attribute removed, it wasn't used KLONG/KLF/STRTOUKL were fixed for long, so now just use long HIDDEN attribute removed. It was for 3 functions. The PROCPS_EXPORT seems to do the same (opposite) thing. likely/unlikely removed from most places, its highly debateable this does anything useful as CPUs have gotten smarter about branches. Re-arranged the includes, ALL external programs should just #include <proc/procps.h> then proc/procps.h includes headers for files that have exported functions. procps.h and the headers it includes should not use items that are not exportable (e.g. hidden functions or macros) they go in procps-private.h
